The following figure shows two steps for installing the Oracle database server software and client software: Through the above process, we know that the server and the client have a file to be configured, the server is the listener configuration file, and the client is the network service name configuration file. The descriptions are as follows: The server listener file is stored in the listener. ora file, which includes the listener protocol, address, and other related information. Howev
